RESUMO
OBJECTIVES: The utility of intraoperative electrocorticography (ECoG)-guided resective surgery for pediatric long-term epilepsy-associated tumors (LEATs) with antiseizure medication (ASM) resistant epilepsy is not supported by robust evidence. As epilepsy networks and their ramifications are different in children from those in adults, the impact of intraoperative ECoG-based tailored resections in predicting prognosis and influencing outcomes may also differ. We evaluated this hypothesis by comparing the outcomes of resections with and without the use of ECoG in children and adults by a randomized study. METHODS: From June 2020 to January 2022, 42 patients (17 children and 25 adults) with LEATs and antiseizure medication (ASM)-resistant epilepsy were randomly assigned to one of the 2 groups (ECoG or no ECoG), prior to surgical resection. The 'no ECoG' arm underwent gross total lesion resection (GTR) without ECoG guidance and the ECoG arm underwent GTR with ECoG guidance and further additional tailored resections, as necessary. Factors evaluated were tumor location, size, lateralization, seizure duration, preoperative antiepileptic drug therapy, pre- and postresection ECoG patterns and tumor histology. Postoperative Engel score and adverse event rates were compared in the pediatric and adult groups of both arms. Eloquent cortex lesions and re-explorations were excluded to avoid confounders. RESULTS: Forty-two patients were included in the study of which 17 patients were in the pediatric cohort (age < 18 years) and 25 in the adult cohort. The mean age in the pediatric group was 11.11 years (SD 4.72) and in the adult group was 29.56 years (SD 9.29). The mean duration of epilepsy was 9.7 years (SD 4.8) in the pediatric group and 10.96 (SD 8.8) in the adult group. The ECoG arm of LEAT resections had 23 patients (9 children and 14 adults) and the non-ECoG arm had 19 patients (8 children and 11 adults). Three children and 3 adults from the ECoG group further underwent ECoG-guided tailored resections (average 1.33 additional tailored resections/per patient.).The histology of the tailored resection specimen was unremarkable in 3/6 (50%).Overall, the commonest histology in both groups was ganglioglioma and the temporal lobe, the commonest site of the lesion. 88.23% of pediatric cases (n = 15/17) had an excellent outcome (Engel Ia) following resection, compared to 84% of adult cases (n = 21/25) at a mean duration of follow-up of 25.76 months in children and 26.72 months in adults (p = 0.405).There was no significant difference in seizure outcomes between the ECoG and no ECoG groups both in children and adults, respectively (p > 0.05). Additional tailored resection did not offer any seizure outcome benefit when compared to the non-tailored resections. CONCLUSIONS: The use of intraoperative electrocorticography in LEATs did not contribute to postoperative seizure outcome benefit in children and adults. No additional advantage or utility was offered by ECoG in children when compared to its use in adults. ECoG-guided additional tailored resections did not offer any additional seizure outcome benefit both in children and adults.

OBJECTIVES: Patients with diabetes have a higher risk of developing chronic kidney disease (CKD). Early detection of CKD through microalbuminuria screening, followed by treatment, delays the progression of CKD. We evaluated the cost-effectiveness of population-based screening of microalbuminuria among normotensive type 2 diabetes mellitus patients aged >40 years compared with no screening scenario using a decision tree combined with the Markov model. METHODS: We considered two scenarios: Scenario I - dipstick microalbuminuria followed by spot-urine albumin-creatinine ratio (ACR) and serum creatinine in sequence; Scenario II - spot urine ACR plus serum creatinine. A mathematical cohort of the target population was simulated over a lifetime horizon with an annual cycle. Data for the model were obtained from secondary resources. The incremental cost-effectiveness ratios (ICERs) were estimated for screening scenarios compared to nonscreening scenario, along with sensitivity analyses. RESULTS: The discounted ICER per quality-adjusted life years gained for annual microalbuminuria screening in the normotensive diabetic population in India were â¹ 24,114 (US$ 308) and â¹ 13,790 (US$ 176) for scenarios I and II, respectively. Annual screening by scenarios I and II resulted in a reduction of 180 and 193 end-stage renal disease (ESRD) cases per 100,000 population, respectively, resulting in a cost saving of â¹ 12.3 and 13.3 Crore spent on ESRD management over 10 years. Both scenarios were also cost-effective even at the screening frequencies of 5 and 10 yearly. CONCLUSION: Microalbuminuria screening was cost-effective at the threshold of one-time GDP per capita in India.

BACKGROUND: Guillain-Barre syndrome (GBS) is one of the most common neurological manifestations associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Although data for a strong causal association is lacking, anecdotal reports, case series and systematic reviews linking the two have emerged in the literature. This prompted us to compare the clinical features, electrophysiology, and outcomes of GBS cases presenting during the pandemic with cases reported during a similar time period prior to the pandemic. MATERIALS AND METHODS: Prospective data of GBS cases diagnosed as per the National Institute of Neurological Disorders and Stroke (NINDS) criteria was collected for a 6-month period (July-December 2021) at three tertiary care teaching hospitals during the coronavirus pandemic and compared with retrospective records-based data of cases prior to the pandemic (January-July 2019). RESULTS: A total of 40 cases were included in the cases, out of which 17 were in the prepandemic and 23 in the postpandemic period. A total of three cases temporally related to coronavirus disease 2019 (COVID-19) infection and four cases following COVID-19 vaccination were seen in the pandemic cohort. The clinical features, electrophysiological features, and outcomes were comparable during both periods. A slightly higher rate of in-hospital complications and single mortality was reported in the postpandemic period. DISCUSSION: The number of GBS hospital admissions, clinical presentation, electrodiagnostic features, and short-term outcomes did not differ significantly between the prepandemic and postpandemic periods; a slightly higher incidence of in-hospital complications was observed during the pandemic period.

BACKGROUND AND OBJECTIVES: Arginine vasopressin (AVP) is an important hormone responsible for maintaining sodium homeostasis after pituitary surgery. The measurement of AVP levels is difficult because of its short half-life (t 1/2 ). Copeptin is a preprohormone of AVP, and it is a more stable peptide, which can be used as surrogate marker for AVP. This study aims to assess the role of copeptin as a predictor of postoperative hyponatremia and hypernatremia in patients undergoing endoscopic pituitary adenoma surgery. METHODS: This prospective study included 50 patients who underwent endoscopic pituitary adenoma surgery. Serum copeptin levels of these patients were assessed (1) preoperatively (C1), (2) at extubation (C2), and (3) postoperative day 4 (C3). Perioperative data regarding fluid and sodium balance were collected from patients. Statistical analysis was done using the above data. RESULTS: The copeptin values were assessed against the sodium disturbances. 100% of patients who developed transient diabetes insipidus had a relative decrease in C2 from C1 ( P - .0002). 88% of patients who developed early hyponatremia had a relative increase in C2 as compared with C1 ( P < .01). 75% of patients who developed delayed hyponatremia had a relative increase in C3 as compared with C1 ( P = .003). CONCLUSION: A relative increase or decrease in early change in copeptin (C2-C1) can predict development of early hyponatremia or transient central diabetes insipidus, respectively. A relative increase in delayed change in copeptin (C3-C1) can predict development of delayed hyponatremia.

Background: Multimorbidity or co-existence of two or more chronic conditions is common and associated with reduced quality of life and increased risk of death. We aimed to estimate the prevalence and pattern of multimorbidity in primary care settings in Kerala and the associated treatment burden, and quality of life. Methods: A cross-sectional survey was conducted among 540 adult participants in Malappuram District, Kerala. A multi-stage cluster sampling method was employed. Hypertension, diabetes, chronic obstructive pulmonary disease, depression and anxiety screening were done by trained medical professionals. The remaining medical conditions were self-reported by the respondent and verified with patient held health records. The health-related quality of life [HRQoL] was measured using the EQ-5D-5L tool. The MTBQ tool was used for measuring the multimorbidity treatment burden. Logistic regression was used to identify variables associated with multi-morbidity. Results: Overall, the prevalence of multi-morbidity was 39.8% (35.7 - 44.1). The prevalence of multi-morbidity among men (42.6%) was relatively higher than that in women (38.1%). Lower educational attainment, higher age group, and overweight or obesity status were independently associated with higher prevalence of multimorbidity. The most common pairs of coexisting chronic conditions reported in the study were hypertension and diabetes in males (66.7%) and females (70.8%). All domains of quality of life were impaired in individuals with multimorbidity. Conclusion: Multimorbidity is a norm and affects two of five participants seeking care in primary care settings in Kerala. The social gradient in the prevalence of multimorbidity was evident with higher prevalence in individuals with low educational attainment. Multimorbidity seriously impairs quality of life and increases treatment burden. The focus of management should move beyond individual diseases, and pivot towards interventions targeting multi-morbidity management, with a specific focus for people living in lower socio-economic strata.
RESUMO
BACKGROUND: Large pituitary adenomas (LPAs), which constitute â¼5%-14% of all pituitary adenomas, are considered challenging tumors owing to their locally aggressive behavior, low gross total resection rate, and high prevalence of visual deficits and hypopituitarism. We evaluated the utility of various extended endoscopic endonasal approaches in maximizing the resection of LPAs and studied the factors affecting the extent of surgical resection. METHODS: A retrospective study of all LPAs (defined as a minimum diameter >3 cm and tumor volume >10 cm3) treated via an endoscopic endonasal approach between January 2015 and December 2020 was performed. The volumetric extent of resection (3-dimensional volumetric analysis software) was correlated with various demographic, tumor-related, pathologic, and immunohistochemical factors and its effects on the clinical outcomes studied. RESULTS: The present study included 106 patients with LPAs. The mean extent of the resection volume was 79.18 ± 21.75 cm3. The factors that affected the extent of resection included the preoperative tumor volume (P = 0.03) and Knosp grade (P = 0.03). The percentage increase in the extent of resection with the use of 2 endonasal corridors was 10.6% and with 3 corridors was 14%. Visual improvement occurred in 82% of patients, and new-onset persistent hormonal insufficiency occurred in 2.9% of patients. Mortality directly related to surgery occurred in 1.8% of cases. CONCLUSIONS: Extended endoscopic endonasal approaches can safely and effectively be used for gross total resection of LPAs. However, we found that the preoperative tumor volume and Knosp grade were significant factors affecting the extent of tumor resection. The use of multiple endoscopic endonasal corridors can increase the volumetric extent of resection for LPAs.

Background: Endoscopic endonasal surgery (EES) requires wide sinonasal dissection to achieve adequate visualisation of anatomical landmarks. This can also result in nasal sequelae like crusting, nasal discharge, and anosmia. Aim: To use the sinonasal outcome test (SNOT) 22 questionnaire to study the postoperative sinonasal morbidity and its recovery in patients who have undergone EES. Materials and Method: Prospective study conducted from November 2017 to May 2018. SNOT-22 questionnaire was administered on patients operated between before EES and then re-administered during outpatient visits at 1 month, 3 months, and 6-12 months following surgery. Results: Results of 46 patients were analyzed. The mean duration of follow-up was 11.8 months. The mean preoperative SNOT-22 score was 2.69 ± 4.95. SNOT-22 score at 1 month was 5.52 ± 6.77, at 3 months follow-up was 0.39 ± 1.02, and after 6 months was 0.30 ± 1.00. In 32 patients with a nasoseptal flap, mean preoperative score was 3.34 ± 5.68 (P = 0.18), one month following surgery it was 6.68 ± 6.88 and at 3 and 6 months following surgery it was 0.56 ± 1.19 and 0.38 ± 1.15. The mean preoperative nasal domain score was 1.022 (±2.13), the postoperative 1 month score was 2.3 ± 3.7, at 3 months following surgery was 0.22 ± 0.82 and after 6 months of surgery was 0.28 ± 0.96. Conclusion: Patients undergoing EES experienced transient worsening of SNOT 22 scores in the first month following surgery and recovered within 3 months of surgery. The improvement was sustained in follow-up visits beyond 6 months of surgery.

BACKGROUND: The isolation from mainstream development activities, together with poverty and inaccessibility to health facilities made the tribal communities specifically vulnerable to various health problems. OBJECTIVES: This study aimed to compare the utilization of antenatal care, immunization, and supplementary nutrition services by tribal and nontribal mothers and its correlates in the selected districts. MATERIALS AND METHODS: The study was a comparative cross-sectional study. The study population comprised tribal and nontribal mothers utilizing antenatal care, immunization, and supplementary nutrition services. A multi-stage cluster sampling strategy was employed for the study. The Chi-square test was used to assess the association between antenatal care services utilization, utilization of immunization services, supplementary nutrition services utilization and sociodemographic variables, and other service characteristics. RESULTS: Effective utilization of antenatal care services was not seen in 5.6% of tribal mothers. The incidence of low-birth weight (≤2500) was significantly more among tribal mothers (31%) when compared to nontribal mothers (15%). The proportion of tribal children receiving complete immunization without delay was 74%, and among nontribal children, it was 78%. Effective immunization coverage was significantly lower among children of tribal mothers with education below high school level. Receipt of take-home ration was reported by nearly 90% of tribal and nontribal mothers. 90% of tribal mothers felt that quality of take-home ration that they received was of good quality. CONCLUSIONS: The comparison of health-care utilization restricted to the domains of antenatal care, immunization services, and supplementary nutrition suggests that the tribal mothers and children had a relatively comparable utilization pattern in most of the indicators measured.
RESUMO
INTRODUCTION: The pathways and mechanisms through which constraints that impede optimal utilization of the government health-care service provisions translate into health inequities among Particularly Vulnerable Tribal Groups seem to be an area that warrants research. OBJECTIVE: The objective is to explore and understand the mechanisms/pathways through which various factors result in health care inequity among the Kattunayakan tribe in Wayanad. MATERIALS AND METHODS: Designed as a qualitative case study, using observations and interviews with mothers, community members, and frontline health-care personnel, the study was conducted in a Kattunayakan hamlet in Wayanad. The data, in the form of digital audio recordings and field notes, were transcribed, coded, and analyzed using a thematic approach. RESULTS AND DISCUSSION: Axes of inquiry like access to health-care institutions, acceptability of the services provided, hurdles faced by the tribes, the health-care personnel, and how the system responded to these issues were explored. Disregard for the identity and culture of the tribes, geographical barriers for utilization and providing health services, proactive efforts from government systems, collaborations with private and professional bodies are important factors that possibly influence health inequities among tribes. CONCLUSION: Acknowledgment of the sociocultural identity of the tribes, gaining their trust, proactive efforts from the government machinery, innovative context-specific programs, strategic partnerships and a departure from the "blame the victim" philosophy are key in the effort to provide services that meet the health-care needs of the tribes.
